Good afternoon.
I would have a leak down test done to check for a failed head gasket. If compression is leaking into the cooling system, it will run hot.

Did you have this test done?

That could be either from a bad radiator cap or you have a leak, such as the head gasket.
You need to have a leak down test done to see if it has a failed gasket.

Just to add to this, are the cooling fans coming on?
I attached some testing which includes the things you replaced but also a few other things that we need to check.
As the engine begins to get to 210 degrees F the fans should be on high, if not then that is the issue. Let us know what you find with all this info. Thanks
